I have a number of battery banks in a camper van and an off grid hut.I have used this with mains and a generator and it works flawlessly in both environments.I have also charged a 130Ah leisure battery that had been fully discharged. I was able charge and use the repair option on the battery within four hours. I then did a ‘drop’ test to look at how much capacity I had lost and it was indicating 95% recovery which is as good as some new batteries I have tested.I am amazed that they are able to get such a high output into such a modest sized unit (although it is huge compared to regular low output chargers).All of the cabling is super high quality.
